To all whom t may con/cem:

Be it known that I, JOHN P. HAYES, citizen of the United States ofAmerica, residing at 19 Joel street, Mount Washington, Pittsburgh, inthe county of Allegheny and State of Pennsylvania, have invented certainnew and useful Improvements in Electric Controllers, of which thefollowing is a specication, reference being had therein to theaccompanying drawing.

This invention relates to an electric controller, and its principalobjects are as follows: first, to start in either direction, at near orremote distances, to automatically cut out resistance in series with anarmature of an electric motor, during the starting, whereby the armatureis brought up to its normal speed gradually, and in the stopping of saidmotor, resistance is automatically inserted in series with the armature,until the circuit is opened to the supply line.

Before entering into the description of the construction and operationsof the con troller, I will here state that -I prefer to use areciprocating electric motor of the type shown and claimed in LettersPatent No. 869,780 granted to me October 29th, 1907, as the prime moverof this controller. In some operations of the controller fairly goodresults can be had when the controller is actuated by rotary electricmotors, electric magnets of the plunger type, reciprocating watermotors, compressed air motors, or steam motors, but for the generalscope for which this invention is intended, I am not aware of any othermeans by which the controller can be actuated to give results as theabove mentioned preferred motor. I therefore, deem it advisable to givea description of the reciprocating motor, in connection with myinvention, so that the operations of the controller throughout thedescription may be more readily understood.

In reference to the drawings which form a part of this specification,Figure 1 is a side elevation of the controller coupled to a two polereciprocating motor. Fig. 2 is a plan of the same. Fig. 3 is an enlargedend view of a motor. Fig. 4 is an enlarged cross sectional view taken onthe line IV-IV of Fig. 1 looking in the direct-ion of the arrow A ofsaid figure. Fig. 5 is a similar view taken on the line V-V of Fig. 2,looking in .of the lock magnet constituting a part of the controller.Fig. 11 is a side elevation of the same. Fig. 12 is a diagrammatic viewshowing the wiring of the controller to a motor, which represents acompound wound rotary motor. Fig. 13 is an eleva- 'tion of a modifiedform of controller coupled to a two lpole reciprocating motor. Fig. 14:is an enlarged detailed sectional view of a portion of the controllerillustrated in Fig. 13 of the drawings. Fig. 15 is a cross sectionalView of the controller taken on the line VV-W of Fig. 13, looking in thedirection of the arrow of said figure.

Fig. 16 is a cross sectional view taken on the line O-O of Fig. 15. Fig.17 is a perspective view of a movable head constituting part of thecontroller illustrated in Fig. 13 of the drawings. Fig. 18 is a verticalsectional View of the same. Fig. 19 is a diagrammatic view showing thewiring of the controller illustrated in Fig. 13 to a compound woundrotary motor.

I will first describe the controller illustrated in Figs. 1 and 2 of thedrawings. Two standards, 51 and 52 are supported by a base 1 and rods51a and 52a extend from the standard'51 to standard 52. On the inside ofstandard 51 are mounted conductor contacts 63a to 68a and on the outsideof said standard are mounted what I term a lock magnet M (but I wish tohave this element construed in the broadest sense) and a circuit breakerGl. A detail of the lock magnet M is shown in Figs. 10 and 11 and adetail of the circuit breaker G1 is illustrated in Figs. 6 and 7. On theinside of standard 52 are mounted conductor cont-acts 69a to 74ainclusive, and upon the outside binding posts P1 to P7 and a circuitbreaker G2 which is identical in form and construction as the one onstandard 51. Between the standards 51 and 52 is a reciprocating head 56movably mounted upon the rods 51a and 52a. Upon each side of the crosshead 56 are coiled springs 57 to 60 inclusive surrounding the rods 51aMand 52a, the purpose of which will be hereinafter described. Attached tothe cross head 56, passing through a bearing in standard 51 andconnected to the shaft of armat-ure 6, by nut 21 is a rod 53. Passingthrough the cross head 56 and suitably secured thereto are rods 61 and62 having longitudinal disposed keyways formed therein. Movably mountedupon said rods and prevented from rotating by keys in said keyways aredisks lV, X, Y, Z, said disks being normally held in engagement withadjustable nuts mounted upon said rods and by coiled springs 57a, 58a,59a, and 60a, surrounding said rods. The disks, WV, X, Y, Z, areprovided with conductor contacts 63 to 74 inclusive, suitably insulatedfrom the disks. These disks are adapted to engage conductor contacts63LL to 74a inclusive, carried by the standards 51 and 52. In Fig. 9 ofthe drawings, I have illustrated the manner in which the disks are keyedupon .the rods 61 and 62, the key 251 carried by the disks engaging in akeyway 7 5b formed in the rods 61 and 62. It will be understood that thedisks IV, X, Y, Z, reciprocate upon these respective rods. Locatedbetween the standards 51 and 52 is a rheostat 50C embodying a suitablesupport secured to the base 1. The support 8Oa is provided withresistance contacts 79 and with pulley supports 80 for guiding a rope 81fastened to the movable head 56 and to the expansion spring 82, saidspring being fastened to an arm 83 having an adjustable weight 84. Inconnection with the lever 83, I use a dash-pot S5 of a conventionalform, the piston rod 86 of said pot being connected to the lever arm.

Reference is now made to Figs. 6 and 7 showing the detail constructionof circuit breakers G1 and G2. These breakers are supported by standards51 and 52 arranged upon the base 1. Secured to the standard 51 arebrackets 91 and ournaled in said brackets is a shaft 90. Loosely mountedupon the shaft are breaker arms 94 and 95 normally held under tension bysprings 92 and 93 surrounding the shaft 90. Resiliently carried by thebreaker arms 94 and 95 is a cross-piece 96, said piece being movablysupported upon bolts 90 carried by said breaker arms. Springs 98 arearranged upon the bolts for normally holding the cross-piece in a fixedposition; nuts 97 and 99 being employed for adjusting springs 93 andcross-piece 96. Mounted upon the standard 51 (an elevation shown in Fig.7 intermediate with breaker arms 94 and 95 are brackets 105 carrying aspring-held pin 104, upon which an angle latch has two arms, 101 and103, the arm 101 engaging a cross-piece 102 carried by the breaker arms94 and 95, while the arm 103 extends upwardly in the rear of thecrosspiece 96. The upper ends of the breaker arms 94 and 95 are providedwith conducting contacts C1 and C2, said contacts engaging contacts el,e2, e3, e4. rlhe circuit breakers are identical upon the standards 51and 52 and their o-peration will hereinafter be deend thereof is a rod112, slidably mounted in a bracket 113. Surrounding rod 112 is a coiledspring 114, resting upon said bracket and retained thereon under tensionby a nut 115 adjustably mounted upon the threaded end of the rod 112.r1`he other end of the core 111 is provided with one part 116 of a softiron clamp, the other part 117 of said clamp being secured to a rod 118slidably mounted in a bracket 119. Guide pins 120 are arranged upon thepart 117 for guiding the part 116. It is evident that the magneticcircuit can be completed by mounting the lock magnet on a magneticconductor.

Referring now to Fig. 13, I have illus trated a modified form of thecontroller coupled to a two pole reciprocating motor El. Standards 51band 52b are supported upon a base 1 and by parallel rods 130 and 131.Upon the inside of standard 51b I arrange resilient adjustable conductorcontacts 1a to 6a and 1r to 5" inclusive of which a detail view is givenin Fig. 14 and a face view given in Fig. 15 showing the contactsarranged on standards 51b and 52h. A further explanation will be givenof these spring contacts hereinafter. Upon the outside of standard 51bare mounted lock magnet M and circuit breaker Gl identical in form andconstruction to those used on controller Fig. 1. Upon the inside of thestandard 521 I arrange resilient adjustable conductor contacts 1b to 6band contacts r1 to inclusive, in a similar manner as on standard 51h; aface view of the contacts of the last named standard being given in Fig.15 which will be described hereinafter. Upon the outside of standard 52bis mounted a circuit breaker G2. Between the standards 511 and 52h, instead of using a rectangular head 56 with resilient conducting contacts`as in the controller of Fig. 1, I use a reciprocating head 127, diskshaped with fixed conductor contacts insulated therefrom; a detail ofsaid head being shown in Figs. 17 and 18 and will be fully explainedhereinafter. The reciprocating head 127 is slidably mounted upon theparallel rods 130 and 131 and surrounding said rods on either side ofthe head 127 are springs 132 and 133, the purpose of the springs 132,133 will be given hereinafter in the operation of the controller.Attached to the head 127 and passing through a bearing in standard 51bis a rod 53 secured to armature shaft by nut 126.

Referring now to Figs. 17 and 1S the head 127 is provided with conductorcontacts al to as inclusive, a short circuiting conductor 140, an arm136 extending through the head with an adjustable nut 137 and bored lugs129. Upon the other side of the head 127 are conductor contacts b1 to 56inclusive and a short circuiting conductor 140a similarly arranged. Byreferring to diagram view Fig. 19, wm shows the side given in theperspective, and x0 the opposite side. Fig. 18 shows rod 136 extendingthrough head 127 with an adjustable nut 13S, the purpose of which willbe hereinafter explained.

Referring now to Fig. 14, I illustrate a detail sectional view ofstandard 51b which shows the form of springs used on standards 51b and52". The springs 150 and 151 are suitably secured to the contact 152 andto the standard 51h, and are movably held by a bolt 153 extendingthrough the standard 51D, and provided with a nut 154 adjustably mountedupon the threaded end of the bolt 153. It is obvious that the springcontacts can be mounted upon a material suitably secured to the standard51h, and that various forms of springs can be used.

The motor employed is shown and described in detail in my Patent 869,780which will disclose any detail features of the device not hereinreferred to.

In Fig. 12, I have illustrated diagrammatically a switch S by which thecircuits are closed and opened in the reciprocating motor E. To avoidconfusion throughout the description, I shall hereinafter refer to thereciprocating motor which actuates the controller, as the actuator,andthe motors that are to be controlled by the controller, as rotarymotors. l

Reference is now made to Fig. 12, which represents a diagrammatic viewof the controller and actuator in the operation of controlling acompound rotary motor L. In this figure, I show adjacently the insideand outside of standard 51 and its mountings and I also show adjacentlythe inside and outside of standard 52 and its mountings. In this Fig. 12and to the right of standard 52, I show a diagram of the connections ofcont-acts on disks WV, X, Y, Z. I have numbers arranged on contacts ofthe last named disks in order to correspond with the contacting ones onthese respective standards 51 and 52, so that the wiring may be morereadily traced, on disk IV contacts 63, 64, and 65 contacts with thecontacts 632, 642, 652, respectively on standard 51. R of Fig. 12 is aresistance of rheostat 50C of Fig. 1 showing contacts 79 and lever 83.In this Fig. 12, I show a manual switch S for closing and opening thecircuits in the actuator E. In the motor L to be cont-rolled Arrepresents the armature bm and bm the brushes Se, the series fields andSL the shunt fields. For a reversible rotation of the armature Ar inmotor L the current is reversed in the armature.

It will be seen in Fig. 12 that the contacts on the standard 51 areconnected by wires 66x and 67W, etc., to contacts on standard 52. In thefirst operation to be hereinafter described, the movable head 56 of Fig1 will move in a direction that the contacts on disk Y Z will engagewith contacts on standard 52, therefore, disks W X and their contactsand the contacts on the inside of standard 51 need not be considered inthe first described operation. By referring again to Fig. 12, it will beseen that all wires from motor L run to binding posts P2, P3, P4, P5,and PG, PT P1 being connected to the positive side of main lines. Nowone of the functions of the disks Y Z with their arrangement of contactsis t0 close the several circuits in the motor L. It will be observedthat six simultaneous points of the circuits may be closed and likewiseopened or the shunt iield contacts can be arranged to be closed earlierand opened later, and it is evident that blow out magnets can bearranged on disks W, X, Y, Z to suppress any arcing at the contactpoints. The cutting out of resistance in motor L will be describedhereinafter. In the second described operation which will be more fullyexplained hereinafter, the movable head 56 moves in a direction thatdisks WV X and their accompanied contacts engage the contacts onstandard 51, and disks Y Z need not be considered. The second operationof the controller in the control of motor L is similar excepting thereversible movement of cross head 56 reverses current in the armaturecircuit Ar which gives to it an opposite rotation. To avoid anyunnecessary complications in tracing out the wiring of motor L it may bewell to remember in the description that motor L has no electricalconnection with circuit breakers G1 G2, lock magnet M, actuator E orswitch S. As the actuator E is the prime mover of t-he cross head 56 thedirect-ion of movement of said cross head therefore depends on directionof movement of armature 6 of the actuator. In this operation, theactuator is shunt wound and I have arranged its armatures circuit inseries with circuit breakers G1 and G2 and I have arranged its iieldcircuit 4 is series with circuit breakers G1 and G2. The lock magnetcircuit M is arranged in circuit with the fields of the actuator inawaythat when circuit breakers G1 and G2 are closed, lock magnet M is shortcircuited, but when either of the circuit breakers GL and G2 is opened,lock magnet M is put in series with the fields of the actuator. Thepurpose of the circuit breakers and lock magnet in this operation isthat when all resistance is cut out of series with motor L, either ofthe circuit breakers G1 or G2 is automatically opened, as willhereinafter be described, .which opens they circuit in the actuatorarmature 6 and puts lock magnet M in series with the actuators fields 4,the lock magnet l/I being now energized, locks the controller. It isevident with the controller lock and magnet M wound with comparativelyline wire, the electrical energy consumed in ields 4 will be very small.

Following is a diagram of connections and operation of the controllerReferring to Figs. 2 and 12, first refer to Fig. 2, it will be seen thatthe contacts are arranged on the standard 52 in the order 69a, a, etc.,up to 74, and directly opposite on the disks Y and Z are arrangedcontacts in the order 69, 70, etc., up to 74. Now by referring to thedisks Y, Z in Fig. 12, it will be seen that contact 69 is connected tocontact 70, and that contact 71 is connected to cond tact 72, and thatcontact 73 is connected to Contact 74, it therefore follows that whenthe contacts on the disks Y Z come in contact with the contacts on thestandard 52, contacts 69a and 70EL are cross connected and 71-72aarecross connected and 73a-74L are cross connected. Upon the contacts ofdisks Y Z engaging t-he contacts on the standard 52 circuits through themotor L, are closed, which are as follows: From the main line 202, thecircuit passes through the switch J to wire 220, binding post P1 tocontact 69a to contact 69 of the disk YY, through wire 69m to contact 70of the same disk, to 70a to binding post P2 to lever 83, throughresistance R to brush bm, through armature Ar to brush 5171/, throughwire Pm to binding post P3 and then t-o contact 716011 the standard tocontact 71 on the disk Y through wire 71m, to contact 72 on the disk Z,to contact 7221 on the standard to binding post P4, through Wire Px tocoil Se, to binding post PT, to wire 221, switch J to main line 203. Theshunt fields circuit is made at binding post P1 and connects to bindingpost P5 by a wire Po, thence to contact 73a, to contact 73 on the disk Zthrough wire 73m to contact 74 of said disk to contact 74a on thestandard, to binding post PG, through wire Xm to shunt coil Sh, throughwire M0 to binding post P7, and then through the wire 221, switch J, tothe main line conductor 203. With the circuit through the motor L, thearmature A1" rotates in the direction of arrow B.

The circuits now will be described of the actuator E, circuit breakersG1 and G2, lock magnet M and switch S.

The main line conductor 200 is connected to contact SL and main lineconductor 201 is connected to S8 of switch S. There are two circuitsleading from the switch S, which are as follows: Vhen the switch S is.closed by moving the lever arm 170 in the dithus closed 'contact 173 tocontact S5, wire 205 of the acto contact c6, wire 207 to contact e3 by acontact on the circuit breaker GL carried by the standard 51. From thiscontact the circuit passes through contact C1 to contact et, wire 208 tocontact S9, through contact 174 to contact S8, and from there to themain line conductor 201, thus completing a circuit which passes throughthe armature 6. The other circuit is from the contact SG through wire209, actuator coils 4 and wire 210 to contact c?, from said contactthrough contact C3 to Contact es, wire 111 to contact e2, throughcontact C to contact el, wire 215 to contact S10, through wire 192 tocontact S7, from said contact to contact 174 carried by the lever 170,to contact S8 and to the main line conductor 201. It will be noted inthe last described circuit that wires 213 and 214 leading from lockmagnet M are shunted across the wires 210 and 215, that is, the lockmagnet M is short circuited through the circuit breakers G1 and G2 andwhen either of said circuit breakers is open lock magnet M is placed inseries with the actuator fields 4. Vhen the circuits above described areclosed, the armature and field windings of the actuator E are energized,setting up relative magnetic fields which cause the armature 6 to movein the direction of the arrow A2, moving with it cross` head 56 withdisks Y Z and their'contacts. Upon these disks engaging the contacts on.the standard 52, circuits through the motor L are closed, the armatureAr rotates as heretofore described, and further operations are asfollows: As armature 6 of the actuator E moves, the rope 81 connected tothe cross head 56, pulls upon the springs 82, moves lever 83 over thecontacts 79 cutting out the resistance R, the dashpot 85, resisting anytoo sudden action of lever 83 in moving over contacts 79. The rods 61and 62 carried by the crosshead 56 pass through the disks Y and Z, andthrough the standard 52, compressing springs 58a and 60a. The springs 58and 60 on the rods 52a and 51a are also compressed. As the rod 61 passesthrough the standard 52, it impinges the crosspiece 96 of the circuitbreaker G2, moving said cross piece on the bolts 90a and compressessprings 98. The nut on the rod 61 is adjusted in order that when thecrosshead 56 travels a suilicient distance to cut out resistance in therheostat 50c, said nut strikes the arm 103, which trips the arm 101engaging the cross-piece 102; the increased tension of the springs 98pressing against the nuts 99 overcomes the tension of the springs 92 and93, opening t-he circuit breaker GZ. The opening of said circuit breakeropens the circuit to the armature 6l and places the fields circuit 4 ofthe actuator E in series with the lock magnet M thereby energizing saidlock magnet and causing it to attract the clamp member 117, causing itto clamp the rod 153, locking the controller until switch S is opened.Vhen the switch S is open the rod 112 and magnet 110 are elevated by thespring 1111, and the clamp member 117 descends to the bracket support119. The springs 58 and 60 return crosshead 56 and the armature 6 to acentral or starting position, opening the circuits to the motor L. Thesprings 92 and 93 immediately close the circuit breaker G2. In thesecond operation of the controller, or the moving of the head 56 in theopposite direction armature Ar of motor L is caused to rotate inopposite directions.

Referring again to Fig. 2, it will be seen on st-andard 51 that thecontacts arranged thereon are in the order 63a, 64a, etc., up to 68a anddirectly opposite on theI disks 1V X are arranged contacts in the order63, 64, etc., up to 68. Referring to the disks, Fig. 12, it will be seenthat contact 63 is connected to contact 64, and that contact 65 isconnected to contact 66, and that contact 67 is connected to contact 68,it therefore follows that when the contacts on disks IV X come incontact with the contacts on standard 51, contacts 63a and 64a are crossconnected, contacts 652l and 66a are cross connected and contacts 67aand 661 are cross connected.

It will be seen in Fig. 12 that on the inside of standard 51, instead ofhaving the contacts thereon connected by wire direct to the binding poston standard 52 I have them connected to the contacts on last saidstandard. In tracing out the circuits, I will neglect mentioning thecontacts on standard 52 considering the wire straight from the contactson standard 51 to the binding posts P2, P3, P4, etc. on standard 52. Thecircuits are from main line conductors 202 through switch J, wire 220 tobinding post- Pl, wire 69x to contact 69a, wire 69W to contact 63a. Fromcontact 63a to contact 63 on the disk 1V, wire 63W, to contact 64, fromsaid contact to contact 64a, wire 64W to contact 71a, wire 71X tobinding post P3 wire Pm to brush bm, through armature Ar to brush Zim,to contact 79, through resistance R to lever 83. From the lever 83, thecircuit is through wire 83m to binding post F2, wire Pe to contact a,wire 70x to contact 65a, to contact- 65 on the disk W, wire 65X tocontact 66 on the disk X, tocontact 66a, wire 66X to contact 7 2a, wirePd to binding post P4, wire Pw to series coil Se, wire M0 to bindingpost PT, wire 221 through switch J to main line 203. The shunt fieldcircuit is from binding post P1 through wire P0 to contact P5, by wireto contact 73a, by wire 73x to contact 67a,

to contact 67 on disk X through wire 67 m to contact 68, to contact 68a,wire 68X to contact 74a, by wire to binding post P6 through wire Xm toshunt coils S71., through wire M0 to binding post I", wire 221 throughswitch J to main line 203. Vith the circuit thus vclosed in motor L,armature Ar rotates in the direction of arrow B. Vhen the switch S isclosed in the direction of the arrow a (see Fig. 12) contact 172 on thelever 170 engages contacts s1, s2, and s3, while contact 175 of saidlever engages contacts 81, 811, and 812. The circuit through thearmature 6 of the actuator E is Vfrom the main line 200 to contact s,wire 190 to contact s", through contact 172 to contact s2, wire 193a tocontact s, wire 208 to contact et, through contact c to contact @3,Wire207 to contact e, through contact o2 to contacts e5, wire 206, througharmature to wire 205 to contact si", wire 193 to contact s, throughcontact 175 to contact 812, wire 193b to contact ss, and from saidcontact to the main line conductor 201. If the switch S is closed, thecircuit is reversed in the armature 6 of the actuator E and moves in thedirection of the arrow A moving with it the crosshead 56, the contactson the disks W X engage the contacts on the standard 51, closing circuitin the motor L, causing the armature Ar to rotate in the direction asheretofore described. The cutting out of the resist-ance R the openingof the circuit breaker G1 and the locking of the magnet M, etc., isidentical in every way in this o-peration as in the first operationheretofore described.

Fig. 19 is a diagram of the circuits of the controller Fig. 13 appliedto a compound wound rotary motor L. One of the objects of the controllerof the modified form Fig. 13 in the operation of controlling a motor isto dispense with sliding contacts which are objectionable when the motoris of large size, wherein heavy currents are used. In Fig. 19, Lrepresents a compound wound motor, Bs represents the armature, Se theseries iields and S71 the shunt fields, R is the resistance. I show inthis figure the inside of standard 51b mounted with resilient contacts1a, 2a, 3a, 4a, 5a, 6a, and similar contacts 1f, 2r, 3f, 4*", 5r, and tothe right of standard 51h, I show the inside of standard 52D, withresilient contacts b1, 792, b3, b4, b5, 56, and similar contacts r1, r2,r3, r, T5, the springs and contacts are identical on the above namedstandard. Contacts on standard 52h are connected by wires 0a, 0b, etc.,to contacts on standard' 51h. Underneath the above described standardsare shown face views of the two sides of crosshead 127. The contacts onthe view wm contacts on standard 51b and the contacts on the View m0engages contacts on standard 52h.. By close inspection it will be seenthat on view wm that a is connected by wire to a2, and

a3 is connected by wire to a4 and a5 is connected by wire to a6 and thatthese contacts will cross connect their reciprocals on standard 511)that is a and a2 will cross 2a and 3, and so on. The functions ofconductor 140 is to short circuit 11, 21', etc. Likewise on view x0, band Z22 are connected together 3 and 64 are connected together, and b1and 511 are connected together and these contacts contact with theirreciprocals on standards 5211 and cross connect in the same manner asdescribed with standard 511. The resilient contacts 12L to 6a inclusiveon the standard 511 areadjusted whereby they will simultaneously contactwith the contacts a to a inclusive on the side com of a disk 127, andthe resilient contacts 11 to 5r which are connected to the resistancecoils 11 to 51 inclusive, will project farther than the subsequent onein the order named.

The first operation to be described of controller 16, crosshead 127 willmove in the direction that the contacts on the side wm of said crossheadwill contact with the contacts on standard 511.

The circuits are closed in the actuator E, circuit breakers Gr G2 andlock magnet M, Fig. 13 in a similar manner as described in Fig. 12, andwhen the circuits are thus closed the armature of the actuator 6 movesin the direction of arrow D moving with it crosshead 127 on the rods 130and 131, compressing springs 132. The rod 136 passes through thestandard 511D and the contacts on the side wm of the crosshead 127engaging with the spring contacts 1a, 2a, 3a, 411, 5, 6a, on standard511 simultaneously closing the circuit throughout motor L 4as heretoforedescribed. As the actuator armature 6 moves the short circuit-ingconductor 140 on crosshead 127 engages the contacts, first 1" then 2r tol5F inclusive, as the conductor 140 on crossheade127 engages with thesucceeding one in the order named, resistance 21 to 5d inclusive are cutout or short circuited in the same order to motor L. The nut 137 isadjusted to trip the latch on circuit breaker G1 when the resistance iscut out of circuit to motor L in the manner and with similar results aspreviously described in connection with Fig. 12 of the drawings. lVhenthe circuits are opened to the actuator, it assumes a central or astarting position opening the circuits to motor L. lVhen the circuitsare closed in the actuator E which causes it to move in the direction ofarrow D moving with it crosshead 127, the contacts on the side XO ofsaid crosshead engages with the contacts on standard 521, this secondoperation in the control of motor L is identical to the first operationas above described, excepting that the current is reversed in armatureBs which gives to it an opposite rotation.

1 desire to call attention that dash pots of a conventional form can bearranged on standards 511 and 521 in combination with springs to assistin the regulation of the movements of the reciprocating head 127.
